nocomo'nvn To all whom it may concern:

Be it known that I IRWIN A. ,SEIDERS, a citizen of the United States, residing in the city of Reading, in the county of Berks, in the State of Pennsylvania, have invented certain new and useful Improvements in Locomotives, of which the following is a tion is to provide spark arresting provisions in the smoke box of a locomotive which will effectively prevent an objectionable discharge of sparks from the locomotive smoke stack while permitting a direct draft not appreciably retarded by the spark arresting provisions and-which will not result in an undesirable accumulation of cinders in the smoke box; and which is characterized by the simplicity, strength and durability of its mechanical construction, and the easy manner in which the provisions may be detached and removed as required to permit inspection, adjustment and repair of the steam pipe connections, etc., at the front end of the locomotive.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a partof this specification.

For a better understanding of the invention,

however, and the advantages possessed by it, reference should be had to the accompanying drawings and descriptive matter in which I have illustrated and described a preferred embodiment of my invention.

Figure 1 is a sectional elevation of a portion of a locomotive embodying .my invention; Fig. 2 is a plan view of a portion of the smoke arresting provisions; andFig. 3 is an end elevation of a locomotive with the right half in section on the line 3-3 of Fig. 1, and with the left half in section on the line 3 a of Fig. 1, but partly broken away to show the spark breaking screen back of the line 3 -3. p

shell; B the front tube sheet; C the fire tube fines; D the smoke box; E the smoke stack; F the divided steam pipe, and G the exhaust pot, and G the exhaust nozzle proper of a locomotive of ordinary construction.

In front of the upper flues C is'a spark breaker plate H. As shown, this plate extends from the level of the upper fire tubes to the top level of the exhaust pot G and thus projects in front of the ma or portion In the form shown, the spark breaker plate is divided vertically into three sections it, h and k which are bolted together. The outer sections it and k are each provided at its upper end with a flange portion H which is secured to an angle plate J secured to the tube sheet B. The side sections of the spark breaker plate are secured to the boiler shell by brackets H, and the spark breaker plate is secured at its lower end by the brackets O to the table M,

hereinafter referred to. The spark breaker plate H is provided with apertures H formed by punching out tongues H which project away from the surface of the plate and are downwardly inclined to deflect cinders or coals passing through the apergures H toward the bottom of the smoke Extending across the smoke box is a table M comprising two downwardly inclined side sections formed of sheet metal, and a horizontal bottom section m. The latter, which seats upon and may be clamped to the exhaust pot Gr, is apertured to form a screen through which small particles may pass. The table M is provided at its front and rear edges with angle bar braces M and M respectively, and the upper edges of the inclined sections of the table are connected to the boiler shell by means of the angle bars M The usual live steam supply pipe 9 for the nozzle G is preferably located below the table M. A screen of wire netting or perforated metal L extends parallel to the spark breaker plate H in front of the latter and is connected at its lower edge to the vertical flange of the angle member M At its upper edge the netting L is clamped against an angle bar K which is secured to the front end of a horizontal metal plate I. The latter is secured to the angle bar J, as shown, being clamped between the bar J and the flanges H of the spark breaker plate H. The side edges of the netting L between the upper edges of the table M and the ends of the plate I are secured to the boiler shell by means of angle bar sections P'riveted to the latter.

A spark arresting screen LA extends from the front edge of the table M to the top of the side of the boiler shell. As shown, this screen comprises a main section and a removable door section LB. The main section is secured to the boiler shell above the level of theside edges of the table M by means of the curved angle bar Q, and at its lower end is secured to the angle bar portion M of the table M. The section LA is formed with a transverse frame member L which forms part of a frame work surrounding the opening normally closed by the removable door or screen section LB. The branches of the .steam pipe F pass through apertures M formed in the inclined portions of the table M. Leakage of cinders or sparks along the joints between the steam pipe branches and the walls of the apertures M isprevented by the sectional sheet metal guards M which are bolted to the inclined portions of the table or jammed snugly about the steam pipe branches.

Located in the portion of the smoke box inclosed between the front and rear screens is a. chimney or mixing nozzle R formed, as

- shown, with an enlarged lower portion R and an axially adjustable upper or telescoping section R". The chimney R is held in place by brackets S secured to the metal stays S extending between the table M at the opposite side edges of the perforated portion m and the portion of the stack E which extends into the upper end of the smoke box.

In operation cinders and burning pieces of fuel discharged from the upper and major portion of the fiues C, strike the spark breaker plate H and if already small enough. pass through the apertures H or are broken up by impact with the plate so that they may pass through the apertures H or are deflected to the lower end of the smoke box below the level of the table M. The solid material passing into the screen inclosed space surrounding the chimney R is either swept out of the smoke stack by the draft or collects on the table M and rattles down on the perforated horizontal portion m of the latter. When in this position, the suction created by the exhaust discharge from the exhaust pot G sweeps these particles, all of which are fine enough to be removed by the draft, up through the chimney R and out of the smoke box through the smoke stack E. The cinders and fuel particles passing out of the flues C below the spark breaker plate H impinge for the most part against the lower ends of the two sections of the pipe F or the exhaust pot G which thus serve as spark breakers. The

particles of solid material collecting on the inner wall of the boiler shell below the table M are continually being sucked up through the apertured portion on of the table M and drawn out of the smoke box through the chimney R and stack E, especially as in the usual operation of the locomotive the particles tending to collect on the bottom wall of the shell are continually being tossed about with the result of breaking up the portions not broken small enough by the spark breaker H to pass through the screens L and LA or the apertured portion m of the table M.

The construction described has numerous important characteristics. Among these are the obvious simplicity and mechanical strength and durability of the structure. The spark arresting provisions are all so supported as to reduce to a practical minimum the possibility of different parts working loose or of joints opening in operation through which an undesirable flow of sparks to the smoke stack could occur. \Vhile the discharge of sparks is thus effectively prevented the provisions made for this purpose do not interfere with a direct draft, on the contrary the gaseous products of combustion discharged from each flue end may pass almost as freely and directly to the smoke stack with the spark breaking provisions employed as they could if these spark breaking provisions were omitted. This insures good combustion and a consequent decrease in coal consumption.

With my construction the exhaust discharge through the exhaust nozzle of the usual size will have ample cinder entraining effect to sweep out of the smoke box the cinders tending to collect on and beneath the table M. This is an important feature for the reason that when it is necessary to decrease the size of the nozzle in order to obtain an increased cinder entraining effect, this inevitably results in an increase in back pressure in the ends of the cylinders. The fact that with the use of my invention the locomotive is practically self-cleaning, because of the powerful direct draft and spark breaking and entraining provisions, is a valuable characteristic of my invention, since it reduces the cost of shop maintenance and avoids the necessity for drawing fires to clean the back of the brick arches and chambers of wide fire box engines. By taking off the removable front panel or door LB, access is provided to the T forming the upper portion of the divided steam pipe F and other parts which it may be desirable to clean, repair, inspect or adjust. The joints at the lower ends of the divided steam pipe F are readily accessible beneath the table M when the .front end of the locomotive shell or smoke box proper is open.

While in accordance with the provisions responding use of other features of the invention.
